By building directly on Swift's powerful type system and syntax, Quiver creates an intuitive bridge between traditional array operations and advanced mathematical concepts. Built as an extension on the standard Array type, the framework embraces Swift's emphasis on readability and expressiveness, offering mathematical operations that feel natural to iOS and macOS developers. As a pure Swift library with zero external dependencies, Quiver runs on every Apple platform — iOS, macOS, watchOS, tvOS, and visionOS — as well as server-side Swift with frameworks like Vapor, Linux environments, and containerized deployments. Features Vector Operations Element-wise arithmetic (+, -, , /) Dot product, magnitude, normalization, distance Angle calculations and vector projections Matrix operations (multiplication, transpose, inverse, determinant) Similarity and Distance Cosine similarity (single and batch) Euclidean distance Top-K selection with labels Duplicate detection and cluster analysis Statistics Central tendency (mean, median, min, max, argmin, argmax) Dispersion (variance, standard deviation, standard error, quartiles, percentiles) — ddof=1 sample-statistics convention by default Typed snapshots — [Double].summary() returns a ColumnSummary with the nine-field descriptive picture; Panel","default_branch":null,"files":null,"tree":[],"storefront":"/r/waynewbishop","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/waynewbishop/quiver/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
